To note in this context is also the fact that currently (Tomcat JDBC Connection Pool 1.1.0.0) several setter-methods in org.apache.tomcat.jdbc.pool.jmx.ConnectionPools
have an empty body.
As long as they are not implemented it is better to remove them (the settermethods, not the getter-methods) from the mbean interface, otherwise the user believes to can change these values, but in truth the changes are not considered at all.

We also ran into this issue recently. For example, it would be very useful to increase max size of the pool without restarting the server.
Is there a traction on this? Would it help if we submit a patch?
